Add letters to folder name

How can I add a text to a folder using R? For example, I want to add "_2015" to a folder name called (rain) to be rain_2015. Note that I want to change the folder name which has files in it.

file.rename() should do it.

suffix <- "_2015"
oldname <-  "rain"
newname <- paste0(oldname, suffix)
file.rename(oldname, newname)
